Since the Enzo-based FXX was launched in 2005, Ferrari has used the XX badge, although it has only ever been applied to extreme track-only vehicles. With the introduction of the SF90 XX Stradale and Spider, it is now making its first appearance on the streets.
The XX twins significantly increase downforce and are notable for being the first Ferrari road vehicles with a conspicuous fixed rear wing since the F50 in 1995. At 155 mph (240 km/h), air traveling below the vehicle, via hood ducts, and over the new rear wing, along with the active wing that is still there, produces 1,169 lbs (530 kg) of downforce, up from 860 lbs (390 kg) at the same speed in the ordinary SF90 Stradale.
The XX has a distinctive appearance thanks to more than just the bolt-on aero aids. Ferrari claims that the headlamps have a lower top profile, the twin squircle rear light units have been replaced with a horizontal light bar, and the rear bodywork has been extended in the form of a 'long tail' racer (guess McLaren will love that). What else did you anticipate from a new automobile in 2023, though?
Even though downforce has been increased, the overall weight of the coupe compared to the stock SF in its lightest Assetto Fiorano specification has only decreased by 22 lbs (10 kg), to 3,439 lbs (1,560 kg). The engine (which weighs 7.7 lbs/3.5 kg) and the innovative carbon sports seats account for the majority of the cost reductions. Although they resemble fixed-back buckets, the two sections are really separated by elastic trim, which should make them much more comfortable for road use and suited for a wider range of drivers. Additionally, they are 1.9 lbs (1.3 kg) lighter than the SF90's single-piece seats.
The 4.0-liter, triple-motor hybrid V8 powertrain received significant attention as a result of a 30 horsepower (30 PS) increase, bringing the total output from 986 horsepower (1,000 PS) to 1,016 horsepower (1,030 PS). The combustion engine increases from 769 horsepower (780 PS) to 786 horsepower (797 PS) thanks to polished intake and exhaust tracts, new pistons, and improved combustion chamber shape. Additionally, instead of 217 horsepower (220 PS), the two front motors and lone rear unit now produce 230 hp (230 PS).
Ferrari has chosen to hold off on announcing a Fiorano lap time in order to store that ostensibly historic information for later. The SF90 XX can reach 62 mph (100 km/h) in 2.3 seconds, compared to 2.5 seconds for a regular SF, and can achieve a peak speed of 199 mph (320 km/h), according to both variants of the vehicle. But such figures don't fully convey the situation. Due to its 3,660 lb (1,660 kg) weight, the Spider travels to 124 mph (200 km/h) in 6.7 seconds, which is two tenths longer than the XX Stradale. However, there is no distinction in terms of the driving range of an electric vehicle. The 7.9 kWh battery and 16-mile (25 km) EV range of the conventional SF are shared by both XX vehicles.
